The Gut-Brain Connection: When Your Body Is Talking,
Listen.
Why does your stomach hurt when you’re stressed? Why do anxiety and GI issues show up together so often?
Here are six key facts to help you understand how your gut and brain are connected, and what you can do about it:
1. Your gut has its own nervous system.The enteric nervous system (ENS), sometimes called the “second brain,” contains over 100 million neurons. It communicates constantly with your brain, especially via the vagus nerve.
Your gut literally talks to your brain, and your brain talks back.
2. Over 90% of your serotonin is made in the gut. Serotonin is a key neurotransmitter involved in mood regulation. While it’s often discussed in terms of brain chemistry, the majority is actually produced in the gastrointestinal tract.
Gut inflammation or imbalance can impact mood and emotional regulation.
3. Stress directly affects gut function. When you’re stressed, your body shifts resources away from digestion. This can cause bloating, cramping, diarrhea, or constipation. Especially if your stress is chronic.
The more your nervous system is in overdrive, the louder your gut may speak.
4. Trauma often shows up in the gut. Research links early life stress and trauma to higher rates of functional GI disorders, including IBS.
If symptoms persist, make sure you are talking about them with a professional who understands this reality. .
5. Anxiety and GI disorders are often linked. People with anxiety are about 2x more likely to also struggle with GI conditions. The relationship goes both ways: gut distress can increase anxiety, and anxiety can worsen gut symptoms.
This isn’t in your head. It’s in your nervous system.
6. Calming the nervous system can improve gut health. Therapeutic approaches that regulate the nervous system, like polyvagal therapy, mindfulness, and EMDR can lead to real, lasting relief.
Calming your body may help heal your gut, not just your mind.
Next time your symptoms flare up, ask yourself:
“What just happened?” or “What am I feeling?”
Sometimes your gut is literally digesting emotion, not just food.
